Function
Astringent Properties: Witch hazel extract is well-known for its natural astringent properties, which help tighten and tone the skin. It can constrict blood vessels, reducing redness and inflammation, and giving the skin a firmer appearance.
Anti-Inflammatory: Witch hazel has anti-inflammatory effects, making it effective in soothing and calming irritated or inflamed skin. It is commonly used to alleviate discomfort associated with conditions like acne, eczema, and minor skin irritations.
Skin Cleansing: Witch hazel extract is a gentle yet effective cleanser. It helps to remove excess oil, dirt, and impurities from the skin, making it a popular ingredient in toners and cleansers.
Antioxidant: Rich in polyphenols, witch hazel extract possesses antioxidant properties that protect the skin from oxidative stress caused by free radicals. This can contribute to preventing premature aging and maintaining overall skin health.
Wound Healing: Witch hazel has mild wound-healing properties. It can aid in the healing process of minor cuts, bruises, and insect bites by promoting cell regeneration and reducing inflammation.
Reduction of Puffiness: Due to its astringent nature, witch hazel extract can help reduce puffiness and swelling, particularly around the eyes. It is sometimes used in formulations targeting under-eye bags and puffiness.
Mild Hydration: Witch hazel extract provides a mild level of hydration to the skin without causing excessive oiliness. This makes it suitable for various skin types, including oily and combination skin.
